TerminalOptions.waitOnExit API

enum WaitOnExitType {
    Never = 0,
    NonZeroExitCode = 1,
    Always = 2
}

export interface TerminalOptions {
    /**
     * Whether the terminal panel should wait before closing when a terminal's process exits.
     */
    waitOnExit?: WaitOnExitType;
}

waitOnExit was originally proposed as a boolean in https://github.com/Microsoft/vscode/issues/15583

I’m working to enable debugging plugin goal of a Maven project, leveraging Java Debugger extension. The workflow is:

1. create a terminal with env MAVEN_OPTS injected, which specifies the listening port (a random free port).
2. send the maven command to the terminal, then the command will run in debug mode.
3. start a Java debug session, attach to the port.

After terminating the debug session, users may still want to re-visit the diagnostic info printed, so I want to i) persist the printed info there. But as the injected env will force all maven commands to run in debug mode, I also want to ii) prevent users from re-using the terminal.

Would also like to bump this FR - currently our workaround for the stanza REPL is to invoke it through a secondary launcher process which waits to exit on input.
